Description

Technical Field

[0002] With the development of the construction industry, the tile industry is rapidly developing towards diversification and higher quality. Marble tiles are made through processes such as high-temperature firing, grinding and polishing, and stain-resistant treatment. Marble tiles have high surface hardness and require a smooth, flat, and oil-resistant surface. Therefore, the requirements for polishing processes are becoming increasingly stringent. In the polishing process of marble tiles, existing polishing machines typically use polishing discs equipped with abrasive blocks. An electric motor drives the polishing disc to rotate at high speed, generally between 1500 rpm and 3000 rpm, mostly with stepless speed regulation, which can be adjusted as needed. During the polishing process, the abrasive blocks and polishing agent work together to rub against the surface of the product to be polished. When producing high-gloss and high-smoothness marble tiles, long-cycle, high-speed fine polishing is required. However, with existing abrasive blocks, the mounting base at the bottom of the abrasive block is prone to cracking under stress during fine polishing, thus affecting the polishing quality of the marble tiles.

To this end, this invention proposes an elastic grinding block for a marble tile polishing machine, which has high structural strength and can adapt to the high-speed, long-cycle use of the polishing machine.

[0004] An elastic grinding block for a marble tile polishing machine according to an embodiment of the present invention includes:

[0005] A support base is provided with a mounting cavity, and the mounting cavity is provided with a plurality of support protrusions; the support protrusions are arranged in pairs on opposite sides of the mounting cavity, and the opposite sides have mutually parallel normal vectors.

[0006] A grinding body is embedded in the mounting cavity, and the outer peripheral wall of the grinding body is provided with a structural groove corresponding to the supporting boss.

[0012] According to some embodiments of the present invention, the elastic layer is provided with a plurality of air-permeable holes.

[0013] According to some embodiments of the present invention, a plurality of drainage grooves are linearly arranged on the grinding layer along the length and width directions, and the drainage grooves divide the grinding layer into multiple grinding heads.

[0017] Beneficial effects:

[0018] According to the present invention, the elastic grinding block for a marble tile polishing machine includes a support base and a grinding body. The support base is mounted on the main shaft of the polishing machine and has an installation cavity with several support bosses. The support bosses are arranged in pairs on opposite sides of the installation cavity, with parallel normal vectors on the opposite sides. The grinding body is embedded in the installation cavity, and its outer peripheral wall has structural grooves corresponding to the support bosses. In this invention, the support base is mounted on the main shaft of the polishing machine and can move with the main shaft. The support base has an installation cavity for accommodating the grinding body. Within the installation cavity, several support bosses are arranged in pairs on opposite sides of the installation cavity, with the normal vectors of these two opposite sides being parallel. This parallel relationship ensures the regularity and symmetry of the support bosses in spatial position. The grinding body directly acts on the surface of the marble tile for polishing, and is embedded in the installation cavity. To better cooperate with the support bosses, structural grooves are provided on the outer peripheral wall of the grinding body corresponding to the positions of the support bosses. When the grinding media is installed into the mounting cavity, the support boss engages with the structural groove of the grinding media, achieving a secure connection between the grinding media and the support base. This allows the grinding media to move along with the support base and spindle for polishing. Through the cooperation of the support boss and the structural groove, the grinding media is firmly installed within the mounting cavity of the support base. During the high-speed rotation of the support base driven by the polishing machine spindle, this connection effectively prevents the grinding media from shaking or shifting, ensuring positional stability during polishing and contributing to improved polishing precision and consistency. The paired support bosses located on relatively parallel sides evenly distribute the force experienced by the grinding media during polishing onto the support base. This avoids excessive localized stress, especially during long-cycle, high-speed fine polishing, effectively reducing the risk of cracking of the grinding media mounting base due to uneven stress and extending the service life of the grinding media and related components.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 3As shown, this utility model discloses an elastic grinding block for a marble tile polishing machine. The elastic grinding block for a marble tile polishing machine includes a support base 100 and a grinding body 200. The support base 100 is provided with an installation cavity 101, and the installation cavity 101 is provided with a plurality of support bosses 110. The support bosses 110 are arranged in pairs on opposite sides 102 in the installation cavity 101, and the opposite sides 102 have mutually parallel normal vectors. The grinding body 200 is embedded in the installation cavity 101, and the outer peripheral wall of the grinding body 200 is provided with a structural groove 211 corresponding to the support bosses 110. Specifically, in this embodiment, the support base 100 is mounted on the spindle of the polishing machine and can move with the spindle. The support base 100 is provided with a mounting cavity 101 for accommodating the grinding body 200. Within the mounting cavity 101, several support bosses 110 are provided. These support bosses 110 are distributed in pairs on opposite sides of the mounting cavity 101, and the normal vectors of these two opposite sides 102 are parallel to each other. Specifically, when the mounting cavity 101 has a regular polyhedral structure, such as a cube or cuboid, the opposite sides 102 are two parallel sides of the cube or cuboid. When the mounting cavity 101 has a structure of revolution, such as a cylinder, the opposite sides 102 are partially symmetrical arc surfaces of the cylinder. This parallel relationship ensures the regularity and symmetry of the support bosses 110 in spatial position. The grinding body 200 directly acts on the surface of the marble tile for polishing, and the grinding body 200 is embedded in the mounting cavity 101. To better mate with the support boss 110, a structural groove 211 is provided on the outer peripheral wall of the grinding body 200 corresponding to the position of the support boss 110. When the grinding body 200 is installed into the mounting cavity 101, the support boss 110 will engage with the structural groove 211 of the grinding body 200, thereby achieving a stable connection between the grinding body 200 and the support base 100. This allows the grinding body 200 to move together with the support base 100 and the spindle for polishing operations. The engagement between the support boss 110 and the structural groove 211 increases the contact area, and the grinding body 200 can be securely installed in the mounting cavity 101 of the support base 100. During the high-speed rotation of the support base 100 driven by the polishing machine spindle, this connection method effectively prevents the grinding body 200 from shaking or shifting, ensuring the stability of the grinding body 200's position during polishing operations and contributing to improved polishing accuracy and consistency. The paired support bosses 110, located on relatively parallel sides, can evenly distribute the force experienced by the grinding body 200 during polishing onto the support base 100. This avoids excessive local stress, and especially during long-cycle, high-speed fine polishing, it effectively reduces the risk of cracking of the grinding body 200 mounting base due to uneven stress, thus extending the service life of the grinding body 200 and related components.

[0030] In some embodiments of this utility model, the support boss 110 is a trapezoidal boss. The bottom of the support boss 110 is fixedly connected to the inner peripheral wall of the support base 100, and the top of the support boss 110 faces the center of the mounting cavity 101. The two sides and the bottom surface of the support boss 110 have an included angle β, where 45°≤β≤85°. Specifically, in this embodiment, the support boss 110 is designed as a trapezoidal boss, and the bottom of the trapezoid is fixedly connected to the inner peripheral wall of the support base 100, providing a larger contact area so that the support boss 110 can be firmly attached to the support base 100, enhancing the stability of the overall structure. During the operation of the polishing machine, it can better withstand the reaction force transmitted from the grinding body 200 and is not easy to loosen or fall off. The two sides and the bottom surface of the support boss 110 have an included angle β, where 45°≤β≤85°. From a mechanical point of view, a suitable included angle can effectively disperse the reaction force applied to the support boss 110 by the grinding body 200 during the polishing process. When the grinding media 200 contacts the surface of the marble tile to be polished and generates friction, it will exert a certain tangential force and upward pressure on the support boss 110. Within this angular range, the support boss 110 can reasonably distribute the tangential force to the inner peripheral wall of the support base 100, avoiding stress concentration at a certain point or in a certain area, thereby improving the load-bearing capacity of the overall structure of the support boss 110 and the support base 100, and preventing damage caused by excessive local stress.

[0031] In some embodiments of this utility model, the support base 100 has a grid-like perforation 120 and a mounting hole 130 on one side of the mounting cavity 101. Specifically, in this embodiment, the grid-like perforation 120 on one side of the support base 100 relative to the mounting cavity 101 can effectively reduce the overall weight of the support base 100. For the support base 100 mounted on the polishing machine spindle, excessive weight may increase the load on the spindle, affecting its operating efficiency and stability. The grid-like perforation 120 design, while ensuring the structural strength of the support base 100 is sufficient to support the grinding body 200 for polishing operations, removes some unnecessary materials and reduces the mass of the support base 100. During the polishing process, the friction between the grinding body 200 and the tile surface generates a large amount of heat, which is transferred to the support base 100. The grid-like perforation 120 structure increases the heat dissipation area of ​​the support base 100, allowing air to circulate in the perforated areas, carrying away heat and thus accelerating the heat dissipation rate of the support base 100. Good heat dissipation prevents the support 100 from overheating and causing a decline in material properties, thus extending its service life. It also helps maintain the normal operating temperature of the grinding media 200, ensuring polishing quality. The device can be mounted on the spindle of a polishing machine via the mounting hole 130.

[0032] In some embodiments of this utility model, the grinding body 200 includes an elastic layer 210 and a grinding layer 220, with a structural groove 211 disposed on the elastic layer 210. Specifically, in this embodiment, the grinding body 200 includes an elastic layer 210, which has a certain elastic deformation capacity. When the grinding body 200 polishes the marble tile, the elastic layer 210 can buffer the impact force generated when the grinding layer 220 contacts the tile surface. This not only protects the grinding layer 220, reducing wear or damage caused by excessive instantaneous impact, but also makes the grinding process more stable. For example, when facing some minor unevenness on the tile surface, the elastic layer 210 can adapt to these undulations through its own elastic deformation, ensuring that the grinding layer 220 maintains good adhesion to the tile surface and ensuring the uniformity of the polishing effect. The grinding layer 220 is the part that directly polishes the marble tile. It is usually made of materials with high hardness and wear resistance, which can effectively remove minor imperfections on the tile surface, improve the smoothness and gloss of the tile surface, and make it reach the expected quality standards. The structural groove 211 is disposed on the elastic layer 210 and engages with the support boss 110 on the support base 100. Because the elastic layer 210 has a certain degree of elasticity, when the support boss 110 is engaged in the structural groove 211, the elastic layer 210 can adapt to the shape and size of the support boss 110 to a certain extent, tightly wrapping the support boss 110 and forming a more stable connection. This stable connection effectively prevents relative displacement between the grinding body 200 and the support base 100 during high-speed operation of the polishing machine, ensuring that the grinding body 200 performs polishing operations stably.

[0033] In some embodiments of this utility model, the elastic layer 210 is provided with reinforcing ribs 212 along its length, and the grinding layer 220 is provided with embedding grooves 221 corresponding to the reinforcing ribs 212. Specifically, in this embodiment, the grinding layer 220 is provided with embedding grooves 221 corresponding to the reinforcing ribs 212, so that the grinding layer 220 and the elastic layer 210 can fit tightly together. When the grinding layer 220 is installed on the elastic layer 210, the reinforcing ribs 212 are embedded in the embedding grooves 221 of the grinding layer 220. This structure is similar to a mortise and tenon joint, which greatly enhances the connection stability between the grinding layer 220 and the elastic layer 210. During the polishing process, the grinding layer 220 and the elastic layer 210 will not easily slide or separate relative to each other, ensuring the integrity and stability of the overall structure of the grinding body 200, which is beneficial to improving the polishing effect.

[0034] In some embodiments of this invention, the elastic layer 210 is made of an elastic material, and the elastic layer 210 and the grinding layer 220 are fixed together by an adhesive. Specifically, in this embodiment, the elastic layer 210 is made of an elastic material, such as silicone, rubber, or synthetic plastic. Elastic materials have good elastic deformation capabilities, effectively buffering the huge impact force generated instantaneously when the grinding body 200 contacts the surface of the marble tile. For example, when the grinding layer 220 encounters minor bumps or unevenness on the tile surface during high-speed friction, the elastic layer 210 can absorb and disperse these impact forces like a spring, preventing the impact force from directly acting on the grinding layer 220, thereby extending the service life of the grinding layer 220.

[0035] In some embodiments of this invention, the elastic layer 210 is provided with a plurality of vent holes 213. Specifically, in this embodiment, when the grinding body 200 is working, the elastic layer 210 is continuously subjected to compression and deformation. Providing the vent holes 213 allows air inside the elastic layer 210 to escape under pressure, preventing excessive internal pressure due to air accumulation. When the elastic layer 210 returns to its original shape, air can re-enter through the vent holes 213, maintaining the internal air pressure balance of the elastic layer 210. This helps maintain the stable elastic properties of the elastic layer 210, ensuring that it can effectively buffer the impact force generated by the contact between the grinding layer 220 and the tile surface during repeated stress and deformation, thus extending the service life of the elastic layer 210.

[0036] In some embodiments of this invention, a plurality of drainage grooves 222 are linearly arranged along the length and width directions on the grinding layer 220, dividing the grinding layer 220 into multiple grinding heads 223. Specifically, in this embodiment, during the polishing process of marble tiles, coolant is typically used to reduce the grinding temperature, reduce dust emissions, and improve polishing quality. The drainage grooves 222 linearly arranged along the length and width directions on the grinding layer 220 can guide the coolant out in a timely manner. As the grinding operation proceeds, coolant will continuously accumulate between the grinding layer 220 and the tile surface. If it cannot be drained in time, it will affect the grinding effect and may even cause the grinding layer 220 to slip. The drainage grooves 222 provide an outlet channel for the coolant, ensuring that the grinding area remains relatively dry, allowing the grinding layer 220 to make better contact with the tile surface and improving grinding efficiency. During the grinding process, some debris and dust are generated. The drainage grooves 222 can also carry away some debris and dust while draining the coolant. Without the drainage grooves 222, these debris and dust might accumulate on the surface of the grinding layer 220, clogging the gaps between the grinding particles and reducing the grinding capability of the grinding layer 220. The presence of the drainage grooves 222 effectively avoids this clogging phenomenon, ensuring that the grinding layer 220 always maintains a good working condition.

[0037] In some embodiments of this invention, the drainage channel 222 has an inverted U-shaped structure. Specifically, in this embodiment, the inverted U-shaped structure has a unique geometric shape with its opening facing downwards and its top curved. This shape can quickly collect the coolant and debris generated during the grinding process. As the grinding body 200 contacts and moves against the tile surface, the coolant and debris naturally flow into the opening of the inverted U-shaped drainage channel 222 and then quickly drain out along the curved bottom. Compared to drainage channels 222 of other shapes, the inverted U-shaped design results in less resistance to water flow, faster drainage speed, and more effective maintenance of the grinding area, ensuring the smooth progress of the grinding work.

[0038] In some embodiments of this invention, the end faces of all grinding heads 223 are on the same curved surface. Specifically, in this embodiment, when the end faces of the grinding heads 223 are on the same curved surface, the grinding force can be distributed more evenly on the tile surface. The curved surface design ensures that the pressure borne by each grinding head 223 when in contact with the tile surface is relatively balanced. This helps prevent problems such as localized wear, scratches, or deformation on the tile surface caused by the grinding force being concentrated on certain grinding heads 223. The uniform distribution of grinding force ensures that the entire tile surface can achieve a consistent grinding effect, improving the quality and appearance of the tile.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
